Correct answer: Roll back to an earlier known good release initially, then use Stackdriver Trace and Logging to diagnose the problem in a development/test/staging environment.
Why this is the answer
The correct strategy prioritizes restoring service quickly and then systematically diagnosing the issue. Rolling back to a known good release immediately resolves the user-facing problem, minimizing impact. Afterward, using Stackdriver Trace and Logging in a non-production environment (development/test/staging) allows for thorough, risk-free debugging without affecting live users. Working with an ISP is unlikely to resolve an application-specific performance issue. Opening a support ticket for network data is a reactive step that doesn't immediately address the user impact, and network data alone might not pinpoint an application code issue. Rolling back and then pushing the problematic release again at a quieter period is risky and could reintroduce the problem to users, even if fewer, before a solution is found.
